[PATCH] D62731: Add support for options -frounding-math, -ftrapping-math, -ffp-model=, and -ffp-exception-behavior=, : Specify floating point behavior

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Currently we emit a warning if you use `-frounding-math`, saying that the option is ignored.  That should have alerted users that they're not getting the correct behavior now.  This patch removes the warning and (IIUC) implements the correct behavior but is over-conservative.  If that's correct, I think that's acceptable and we don't need an "experimental" flag or a warning.
